Applcation filed December 15, 1906. Serial No. 348,035.

To all whom it may concern:

Be it known that l, IRA OTIs .THORLE.Y, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Advertising Device, of which the following is a full, clear, and eX- act description.

This invention relates to im rovements in advertising devices particularfy adapted for use in cars for indicating stations or streets, the objectbeing to provide a device of this character that will be simple in construction and in which are two sets of reversible or transferable slides bearing ,advertising matter, such for instance, as the names of streets or stations. i

I .will describe an advertising device embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. Figure 1 is a sectional view on the line 1 1 of Fig. 2, of an advertising device embodying my invention; Fig. 2 isan endview with the end of the casing removed Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. 4 is a section on the line 4-4 of Fig. 2 fFig. 5 is a section on the line 5-5 of Fig. 4; Fig. 6 is a side elevation of the mechanism for preventing the return of the operating bar before it has completed the full stroke, the bar being in the intermediate position; and Fig. 7 is a view similar to Fig. 6, but showing the parts in the position occupied when the bar is at the end of its stroke.

The device comprises a casing 10 containing a series of slides and having lat one side a sight opening 11 and at the opposite side a sight opening 12 through which the slides may be observed, as will be hereinafter described, the sight openings being so arranged that when the casing is turned or reversed, one opening will be above the other.

Extended longitudinally through the casing is a shaft 13 which has bearings in brackets 14 attached to the wall of a car, or to a similar support, and the casing is held as adjusted by turning movement in the brackets, by means of pins 15 slidable in the brackets or in the central portions 16 thereof and adapted to engage in perforations formed'in lugs 17 on the casing. T hese locking pins 15 are held yieldingly in engagement with the lugs by means of springs 18. Arranged in the casing are two sets of slides 19, 20, each slide comprising aframe having a slot at its ends, as indicated at 21, for receiving flanges 22 projecting inward from the endv walls of the casing. One pair of flanges extends from what may be termed the rear wall of the casing and terminates inward of the front wall thereof, so that the slide may pass between the ends of said flanges and said front wall, while the other pairof flanges extends from the front wall andterminates inward of the 'rear wall, thus providing a `space throughv which a slide may be moved. It is designed that, in passing along a street and approachingl a corner, a slide shall be transferred from the upper set tothe rear side of thelower set, and that the slide at the front end of the lower set shall be transferred to thevrear side of the upper set.

-As ameans for transferring .the slides l employ a shifting device consisting of two racks 23, 241 mounted on the shaft 13 and located in chambers on the ends of the casing. rllhese racks engage with corresponding vertically movable racks 25 each of which has pins 26 passing through a slot 27 in the inner end wall of the casing and connecting with a sliding member in the form of a plate 28 carrying a pawl 29, the said pawlbeing pivoted .to the plate and pressed forward by means of a 'spring 30 to engage its free end with the wall of the slide or notch in the end of the foremost slide, as indicated in FigQ 5. Of course, there will be a pawl at each end of each series of slides and when the segment rack device is turned, the lowermost slide will be moved upward to the rear of theuppermost series of slides, while the front slide of the upper'serieswill be moved downward to the rear side of the lower series, so that streets or stations will be indicated upon the return trip by reversing the casing. The set of slides 19 is pressed forward by means of a spring31 mounted in the casing land engaging at its free end with the rear slide of said set and the set of slides 20 is pressed forward by means of a similar spring 32. These springs are curved at the. ends sothat by themanipulation of the segment .racks the pawls 29 will force `a slide from one division' to the other, and the yend slides are yieldingly held in position by means of spring plates or holders 33 which will yield to permit the end slides '.to pass from one position to the other. The segmental racks 23 and 24 are provided with arms 48 and links 47 connected to a horizontally slidable bar 34, the ends of which project through slots 35 in the lower portion of the end walls of the casing and this bar 34 is pressed forward by means of springs 36. rlhe bar 34 has link connections 37 with an operating bar 38 and from the links 37 auxiliary links 39 extend and have pins 40 pro- -iected into slots 41 formed in the operating bar. This operating bar at one end extends outward through an opening' in the casing, as clearly illustrated in Fig. 4.

/Vhen the bar 38 is drawn outward the links 39 and the links 37 cause the bar 34 to move laterally, and by reason of the links 47 and the arm 48 of the segmental racks, the latter are caused to rotate a definite distance each time the bar 38 is pulled out. The racks 25 are moved longitudinallyT by the segmental racks, and as each is provided with means for engaging with one oithe slides, they serve to move the slides in a lateral direction. Thus at each outward movement of the bar 38, a slide is moved from the 'front of the upper series to the rear of the lower series, and one from the front of the lower series to the rear of the upper. In order to insure the movement of the bar 38 to the limiting p osition and secure the full movement of the slides, the said bar is provided with a downwardlyextending rack 43 adapted to engage with the latch 42. The latch is provided with two lateral extensions 42a and 42b (see Fig. 4), one ot which 42"L lies underneath the rack teeth and is adapted to be pressed upward into engagement with said teeth by the spring 44. rlhe other extension 42b rests upon the upper surface of the rack bar and is raised to move the opposite end out of engagement with the teeth when' the cam 46 on the upper side of the rack bar passes beneath. said extension and the bar 38 has reached its limiting position. The angle lever 45 which is pivoted adjacent the end of the latch 42 is normally pressed into engagement with the end of the latch by a suitable spring, but this engagement does not interfere with the free movement of the latch, when the opposite end thereof is engaged by the several teeth. When the latch is operated by the wedge 46, the angle lever 45 engages in a recess in the latch and holds it in such a position that it cannot engage with the teeth while the bar is being returned to its original position. In Fig. 4 of the drawings, the bar is shown in its innermost position, while in Fig. 6, the bar is shown moved outward a short distance. In Fig. 7, the bar 38 is shown moved outward to its limiting position and the wedge 46 in engagement with the latch 42 moves the latter out of engagement with the rack teeth and permits of its being held in this position by the angle lever 45. When the bar 38 is returned to its original position, a cam 46a on the under side of the rack bar .adjacent the ing means, a shaft on which the segment racks are mounted, arms extending from the segment racks, a bar slidable in the casing, springs for moving said bar in one direction, connections between said bar and the arms extending from the segment racks, a longitudinally movable operating bar having link connection with the first-mentioned bar, and means for limiting the longitudinal movement of the operating bar.

2. A device of the class described comprising a casing, two sets of slides mounted in the casing, each of said slides having a trame slotted at its ends, iianges in the end walls of the casing for engaging in said slots, the said ianges terminating inward of the sides of the casing, plates mounted to slide in the casing, pawls carried by said plates for engaging in thex slots of the slides, racks attached to said plates, segment racks at the ends of the casing and engaging with the iirst-named racks, a shaft on which said segment racks are mounted, a s ring-pressed bar having link connection with said segment rack, and an operating bar having link connection with said spring-pressed bar.

3. A device of the class described comprising a casing, two sets of advertising slides arranged in the casing, each of said slides being slotted at its ends, flanges in the ends of the casing for engaging the slots in said slides, the ends of said flanges terminating inward of the sides oi" the casing, sliding plates on the ends of the casing, springpressed pawls carried by the plates and adapted to engage with the slots of said slides,
